Could you update your graphics driver and try again?
Well, I use the graphic driver from Debian Squeeze packages which are updated to the most recent version available. (chpiset intel i915 ) Please note that Firefox 10.0 is not affected by this problem.
Is your graphics driver blocked in F10 in about:support too?
Yes it is blocked: I have read somewhere that acceleration was desactived by default in Linux. GPU Accelerated Windows0/1. Blocked for your graphics driver version.
I tried with FF nightly build 16.0a1 (2012-06-11): The problem is solved !
Cool! Thanks for verifying.
